Office - How to enter a blank line in a message?

I just upgraded from Communicator 2005 to Communicator 2007.

Previously, when composing a message, I could press Ctrl-Enter to
insert a blank line in the message.  But under the 2007 version, this
does not work (nothing happens).

Pressing Enter by itself results in the message being sent, as in the
2005 version.

Is there isome way to insert blank lines in a Communicator 2007 message?

I just ran into the same thing going from the 2007 to 2007 R2 client.
Seems it has been changed to Shift-Enter now - hth!
